• In some installations that have fiber optic service
(digital service to the building, analog service
within the building) the signals to the extensions
may not support the call privacy feature.
• The Do Not Disturb feature is activated at the
extension you are calling.
• There is a call on hold at this extension. Press
and release the LINE button of the call on hold
to return to the call and turn off the reminder
beep.
• This phone will operate during a power failure if
a working battery has been installed. You will be
able to answer calls with the handset, and dial
calls using the dial pad keys and the one-touch
or redial features. No other features will work
until power is restored. All programming is
retained during a power failure.
• The phone has been disconnected from AC
power. When AC power is restored, the screen will
return to the usual display. One touch and
redial numbers are retained until power is re
stored.
• Make sure the power cord is connected to both
the phone and an electrical outlet not controlled
by a wall switch.
• If you have a headset plugged into the telephone,
try unplugging it and firmly plugging it in again.
• Disconnect the telephone base from the modular
jack and plug in another corded telephone. If calls
are still not clear, the problem is probably in the
wiring or local service. Contact your local service
company (charges may apply).
• If you are using the speakerphone when this
problem occurs, eliminate any background noise.
Noise from the television, radio, or other appliances
may cause the speakerphone to cut in and out.
Try engaging the [MUTE] button when you are not
speaking or eliminating the background noise.
